What technical due diligence must answer
The question is not whether the code is elegant. The question is whether the system can be sold, operated, and evolved without multiplying support, security risk, or cloud cost.
A good review connects technical findings to business impact: enterprise readiness, onboarding, uptime, margin, roadmap speed, and legal risk.
Chapter 02
The seven areas you cannot skip
The review must cover architecture, security, data, quality, operations, delivery, and debt. If you only review repositories, you will miss risks that appear in production and sales.
- Architecture: boundaries, dependencies, scalability, and single points of failure.
- Security: auth, permissions, secrets, audit, and sensitive data.
- Operations: observability, incidents, backups, runbooks, and support.
- Delivery: tests, CI/CD, review, ownership, and real velocity.
Chapter 03
The output should be a decision, not a list
The final report should prioritize risks by impact and urgency: what blocks investment, what blocks enterprise sales, what can wait, and what must be fixed before scaling.
